/usr/share/zfs/compatibility.d/openzfs-2.1-freebsd vs. openzfs-2.1-linux vs. FreeBSD main [so: 14]: edonr status

I just noticed that main reports that my pools were created
implicitly matching openzfs-2.1-freebsd (and without
an explicit compatibility assignment) but, under main, zpool
import and zpool status for those pools report a new, disabled
feature. Turns out the issue matches what the diff below shows
as present for openzfs-2.1-linux but not for
openzfs-2.1-freebsd :

So I've taken to updating my existing zpool's via:

zpool set compatibility=openzfs-2.1-freebsd NAME

because I use them under releng/13 and stable/13 and main
and do not want edonr accidentally enabled.

It is not obvious to me if edonr being present for main
is deliberate or not.

For reference:

I happened to do this activity in a aarch64 context, in
case that matters.
